Add subtitles from internet as VTT tracks to HTML5 video element on the page
Provides a page action (icon on the address bar) for selected sites (as specified in extension options). When page action is clicked a search is made to podnapisi.net for a subtitle matching the video element on the page or in an iframe.
If a subtitle is found it's added as track element to the video. Meaning that you'll get subtitles to a video that otherwise would have none. :)
